Title: Product metering apparatus
IPC: A01J21/02
Filed: 1961-07-07
Abstract: 943,851. Delivering measured quantities. LYNCH CORPORATION. July 7, 1961, No. 24762/61. Heading B8N. In a rotary valve butter-dispensing machine the pressure of butter supplied to the measuring valve is controlled by a variable volume constant pressure device in the valve-delivery conduit comprising a sliding U-tube which deflects, trombone fashion, under a constant restoring force. The constant pressure device is shown in Fig. 2 and comprises the U-tube 30 mounted on a cross-arm 32 and having limbs 26 and 28 sliding in bores 80, 82. The cross-arm 32 is connected by rod 36 to a piston 40 working in a cylinder 38. Piston 40, and consequently the U-tube, is forced downwardly by compressed air taken at constant pressure from a reservoir tank. The control valve is shown in Fig. 4 and comprises the drum 94 rotating with shaft 78 in a casing 88 having an inlet port 90 and an outlet 92. The drum has a transverse bore 96 in which a free piston 102 reciprocates. The piston 102 has a slot 104, Fig. 5, through which pass sliding wedges 106, 108, fast with the drum. Wedge 108 is driven by a screw 110, connected to finger wheel 112 and a Vernier scale 114, to adjust the stroke of piston 102 and in consequence vary the quantity of butter it dispenses. In the position illustrated, butter entering at port 90 forces the piston down to expel butter from port 92. By rotating the drum through 180 degrees a fresh charge of butter is presented to the outlet and another charge is taken from the inlet. The complete dispensing system is shown in Fig. 3, where butter from a store T<SP>1</SP> is fed to tank T<SP>2</SP> from which it is pumped through a cooler and mixer 10 to a relief valve V<SP>1</SP>. Bypass 12 from the relief valve returns butter to tank T<SP>2</SP> but the bulk is fed to the constant pressure variable volume device C as described above. Compressed air for the device is taken from a tank 44. When the U-tube 30 is fully extended it connects by-pass 86 having a hot water jacket 124 to return butter to the tank T<SP>2</SP>. Butter is fed from the valve V<SP>2</SP> into a dispensing chamber 54 where it is set and from which it is extruded into a cavity in a reciprocating plunger 60. The plunger 60 is coupled to the valve shaft 78 so that each time the valve dispenses a measured quantity of butter an equal volume is extruded into the plunger cavity and a star wheel and pinion 74, 76, works the plunger to separate and raise this quantity of butter to the position 63 from which it is ejected by a ram 65 into a wrapper 67. U.S.A. Specifications 2,013,025 and 2,592,793 are referred to.
Patent GB-729058-A (GB)
Title: Improvements in or relating to a binary-decade electronic counter
IPC: H03K23/82
Filed: 1952-10-03
Abstract: 729,058. Multi-stable state circuits. INTERNATIONAL BUSINESS MACHINES CORPORATION. Oct. 3, 1952 [Dec. 21, 1951], No. 24811/52. Class 40 (6). [Also in Group XIX] In a binary decade electronic counter comprising bi-stable trigger circuits, and input crystal diodes, each corresponding to a different trigger, connected in series with a source of pulses to be counted, each trigger is connected to the two terminals of its diode by means for switching the trigger to one and the other stable condition respectively in response to the pulses, except that one preselected trigger has one of its connections made to a terminal of a diode corresponding to another trigger. As described, the binary-decade counter, Fig. 4, employs four trigger circuits, similar to that shown in Fig. 3, each comprising a secondary-emission-type tube which is triggered between conditions (DOWN and UP) corresponding to points D and U on its characteristic, Fig. la, by applying pulses to the dynode. The tube 10, Fig. 3, has a constant positive voltage applied to its collector 12, and its dynode 13 is connected in a circuit for applying positive and negative pulses to it alternately in response to positive input pulses at terminal 25. Assuming that the trigger circuit is initially in the DOWN condition, the first input pulse causes conduction through diode 47 and the application of a positive pulse to the dynode 13 through condenser 45 and diode 16. The circuit is then in the UP condition, and the higher dynode potential, applied through cathode follower 40 to points 48 and J2 prevents conduction through diode 47 and allows the next input pulse to cause conduction through diode 35 thus raising the grid potential of tube 17 which then conducts and applies a negative pulse to the dynode from its anode to return the circuit to the DOWN condition. In the counter trigger stages T1, T8, T2, T4, Fig. 4, in which tubes 60, 61., CF 62 correspond respectively to 10, 17, 40, Fig. 3, diodes 69, 90, 91, 92 (corresponding to 47) are connected in series so that the input pulses applied at 70 can only operate a stage if all stages to the left are in the DOWN condition. To effect decade operation of the counter, the condenser 66 (corresponding to 45) if stage T8 is connected not to diode 90 but to the diode 92 of stage T4. As described, all stages are initially in the DOWN condition and are therefore triggered to the UP condition by the first pulse. The next pulse returns T1 to the DOWN condition, so that the third pulse can pass through diode 69 to return T8 to the DOWN condition, all other stages then being in the UP condition. Normal binary operation of T1, T2, T4 occurs in response to the next seven pulses, after which the counter is returned to the initial state,

Abstract: 501,933. Winding-apparatus. LOGAN, H. H. Sept. 14, 1937, No. 25028. Convention date, Sept. 14, 1936. [Class 78 (v)] In means for controlling the retardation of a mine cage at a predetermined point in its travel by means of a rotary cam, the movements of which correspond with those of the cage, the cam is driven by the cage only during that part of its travel when retardation must be controlled. The cam 200, Fig. 2, is mounted adjustably on a spider 205 which is free on a shaft 209 driven through reduction gearing by the winding drum. An axially extending hub member 206 is secured to the spider, and is formed with a threaded bore 213 which receives a threaded sleeve 207 slidably mounted on and keyed to the shaft 209. A dog 212 on the member 206 is engaged by a similar dog 211 on a flange 215 of the sleeve 207 towards the end of the run and the cam is rotated to effect the required retardation. When hoisting or lowering commences, a'weight connected by a chain to a ring 218 clamped 'on the member 206, rotates the cam and dog 212 until an arm on the ring engages a stop. When this occurs, the sleeve 207 has moved axially a sufficient distance for the dog 211 to pass the dog 212 without interference, and the cam has taken up its initial position for the retarding operation on the return journey of the cage. In a modification, means are provided for rotating the cam to change the limits of travel. A sliding sleeve placed between the shaft 209 and the sleeve 207 has spiral slots formed in it which are engaged by a pin passed through the shaft. The driving feather 210 is mounted in the outer surface of the sliding sleeve. When the sliding sleeve is moved longitudinally, it will rotate the sleeve 207 through a part of a revolution, and if the dogs are engaged, the cam will be moved through the same angular distance.

Abstract: 845,162. Hats. ZECHBAUER, C. M., and FROEB, G. Aug. 7, 1958 [Aug. 24, 1957], No. 25350/58. Class 63 [Also in Group VIII] Hats are made of a material comprising two covering layers of fur or wool and an intermediate layer of synthetic fibres of such kind that when the material is exposed to heat treatment the synthetic fibres harden and shrink to effect a stiffening of the intermediate layer. The fibres of polyvinyl chloride and/or polyacrylonitrile are especially suitable for the intermediate layer. In one example given, on a cone-carding machine a layer of wool, thereupon a layer of fibres of polyvinyl chloride and polyacrylonitrile and again a layer of wool are laid. The body is felted, hardened, dyed and then brim-stiffened and blocked in hot water. The hat is then placed for a period in superheated steam of about 150‹C. which effects the stiffening of the intermediate layer.
